Disclaimer: I have been in dealership "management" since 1980, so I have seen my fair share of District Manager Aftersales (current GM name for your rep).
What do you think of your current representative? I am not interested in personal attacks. I want to know what you think of his / her ability / training / authority to actually do their job.
Of course that brings up another point - What do you think their (DMA's) job actually is?
Does your DMA do the whole dealership? Sales & Service / Parts? Or just part of it?
I am completely surprised each time our DMA shows up at the dealership. Why? It amazes me that they continue to show up when they haven't completed the promises / tasks from the last visit. Either ours is incredibly overworked or completely without a clue as to how to perform the task.
